# Question: Can V1 Be Greater Than VR?

## Why do pilots say heavy?

The word “heavy” means a larger aircraft type, with a Maximum Takeoff Weight of 160 tonnes or more.

These aircraft create wake turbulence from their wings and require extra separation between following aircraft, and the use of “heavy” reminds other pilots of that fact..

## What does 3 stripes on a pilot mean?

A flight engineer or a second officer wears two stripes. A first officer, also called a co-pilot or second in command, wears three stripes. A captain, or a pilot in command, wears four stripes. … Pilots also typically wear a winged badge indicating their qualification to fly and their seniority.

## Is 121.5 still monitored?

Flight Service Stations will con- tinue to monitor 121.5 MHz, and aircraft pilots are technically still required to monitor this frequency at all times if it’s possible with installed equipment. After all, 121.5 MHz still remains the GARD frequency for airborne emergencies.

## Can v1 be less than VMCG?

V1 is also the minimum speed at which a pilot can continue a takeoff after an engine failure. If an engine failure is detected after V1, the takeoff must be continued. This implies that the aircraft must be controllable on ground. Therefore, V1 is always greater than VMCG.

## Why does v1 increase with weight?

Since VR and V2 are directly related to weight, for an average runway, V1 will also be higher as weight increases since acceleration and deceleration are both a function of weight.

## How is v1 calculated?

V1 is determined by several factors but the one most important factor is called the “accelerate / decelerate distance”. In other words, the distance it will take to stop the aircraft before the aircraft runs out of runway or continue safely into the air.

## What happens to v1 on a wet runway?

Any help and insight is appreciated. My best answer is that V1 should decrease on a WET runway, because the accelerate stop distance decreases to a greater degree than the accelerate go distance (deceleration is a greater problem than acceleration).

## What is VMBE?

The maximum brake energy speed. It is a function of the gross weight, altitude, temperature, runway slope, wind component, and braking configuration.

## What does v1 VR and v2 mean?

A: V1 is the speed by which time the decision to continue flight if an engine fails has been made. It can be said that V1 is the “commit to fly” speed. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed.

## What does squawk 7777 mean?

§ military interception§ military interception (US) (“Under no circumstances should a pilot of a civil aircraft operate the transponder on Code 7777. This code is reserved for military interceptor operations.”) § non-discrete code used by fixed test transponders (RABMs) to check correctness of radar stations (BITE).

## What affects v1 speed?

Airport elevation, the existence of any slope on the runway, and the presence of precipitation or ice also play a role. Temperature and wind speed are also factors, as are configuration of the airplane. The bigger the airplane, the higher V1 will be, since the airspeed depends on weight.

## What is meant by a balanced field length?

For a given aircraft weight, engine thrust, aircraft configuration, and runway condition, the shortest runway length that complies with safety regulations is the balanced field length. … The balanced field length is the shortest field length at which a balanced field takeoff can be performed.

## What is v1 and VR in aviation?

V1 is defined as the speed beyond which the take-off should no longer be aborted. … Vr or Rotate is defined as the speed at which the pilot begins to apply control inputs to make the aircraft nose to pitch up, after which it leaves the ground.

## Why do pilots say Niner?

The reason for these somewhat strange pronunciations is to encourage the pilot/controller to enunciate clearly, so that the numbers are clearly understood. … The reason for “Niner” is that “Nine” can be easily muffled, slurred, or confused with other words (particularly the number Five/Fife).

## How is v2 calculated?

V2 is closely tied to the rotate speed. If you suffer an engine failure at V1 (which is at some point in the take-off roll and is the worst time to have an engine failure) and then rotate at the correct rotate speed, you will achieve V2 by 35′. The rotate speed is selected so that this will happen.

## What does squawk mode Charlie mean?

This key can also be labeled “NORM”. If you hear a controller tell you to “Squawk normal” or “Squawk Mode Charlie” This is what they mean. IDENT- This function on your transponder puts a special mark on the controller’s screen that lets him know that it is you who are “Identing”.

## What do pilots say before landing?

Before, or during the descent, the Captain will usually make an announcement with local time and temperature at the destination airport, and time left until arrival. It is followed by an announcement from the flight attendant. … “Cabin crew, please take your seats for landing.”

## What does squawk 2000 mean?

The purpose of squawk code 2000 is to prevent aircraft entering a Secondary Surveillance Radar (SSR) area from transmitting a code that is the same as a discrete code assigned by ATC to an individual aircraft. If you are flying in the USA under Visual Flight Rules (VFR), you will be assigned (implicitly) code 1200.
